This is all the hair that came out of my head when I brushed it this morning. It's not an unusual amount. I've read humans lose about 100 strands a day, which seems to me mathematically impossible. Even as I stare at this clump in my hand, I can't believe this happens. If I had short hair like men usually have, OK. I can see that. But my hair reaches my lower back. How am I losing 100 strands every day and still maintain my length? It takes about a month to grow a centimeter. This shouldn't be happening.
